The future of mobile access starts with openness

For global organizations future proofing their access, choosing between proprietary and non-proprietary mobile access solutions is a critical choice that impacts flexibility, security, scalability, and long-term costs.

The advantage of open standard solutions

Open standard mobile access credentials are built on open standards, not tied to a single manufacturer. They are designed to work across multiple platforms, devices, and systems.

Why it matters:

  • Seamless integration across systems
  • Flexibility to choose best-in-class hardware and software
  • Lower total cost of ownership
  • Scalable and future-ready infrastructure

Make the shift to open standard mobile access

The transition to mobile credentials is inevitable but how organizations implement it matters. Proprietary systems may offer short-term simplicity, but they limit long-term growth. Non-proprietary solutions like Sentry Interactive’s mobile credential SDK are built on open standards like PKOC provide a more flexible, secure, and sustainable path forward.

Introducing PKOC: The open standard for credentials

The Public Key Open Credential (PKOC) specification represents a major shift toward open, secure, and interoperable access. Sentry Interactive’s mobile credential software for enterprise access control systems is based on the PKOC framework, pioneering the best security and interoperability standards. 

What PKOC delivers

PKOC aligns physical access control with modern IT security practices, enabling organizations to unify identity and access management.

  • Standardized architecture for cross-platform interoperability
  • Support for NFC, BLE, and UWB technologies
  • Elimination of vendor lock-in
  • Secure authentication using asymmetric cryptography

Built on modern security principles

Non-proprietary solutions based on PKOC leverage asymmetric public-private key infrastructure (PKI), offering a stronger and more transparent security model.

  • Protection against credential cloning and replay attacks
  • Quantum-ready encryption (256-bit minimum)
  • Improved auditability and transparency
  • Compatibility with cloud identity platforms

Open, scalable, and ready for the future

Solutions built on open standards enable organizations to deploy mobile credentials at scale without being tied to a single vendor. Organizations can innovate faster, adapt to new technologies, and future-proof their access strategies.

  • Deploy across diverse environments with ease
  • Integrate with existing access control systems
  • Avoid restrictive licensing models
  • Maintain full control over your infrastructure

Frequently asked questions

What is the difference between proprietary and non-proprietary mobile access credentials?

Proprietary mobile access credentials are controlled by a single vendor and operate within a closed ecosystem, often requiring specific hardware and software. Non-proprietary mobile credentials are built on open standards, allowing them to work across multiple platforms, devices, and access control systems, giving organizations greater flexibility and interoperability.

Why do proprietary mobile credential solutions lead to vendor lock-in?

Proprietary solutions rely on vendor-specific formats, hardware, and licensing models, which tie organizations to a single provider. This makes it difficult and costly to switch vendors, integrate third-party systems, or scale infrastructure without ongoing dependency on that provider.

What are the benefits of non-proprietary mobile access credentials?

Non-proprietary mobile credentials offer greater flexibility, improved interoperability, and reduced reliance on a single vendor. They also eliminate licensing restrictions, lower total cost of ownership, and allow organizations to choose the best hardware and software for their needs.

How do non-proprietary mobile credentials improve security?

Non-proprietary solutions often use modern security frameworks such as asymmetric (public-private key) cryptography. This approach enhances protection against credential cloning and replay attacks, improves transparency, and aligns with current IT security best practices, unlike many proprietary systems that rely on older symmetric encryption methods.

What role does PKOC play in non-proprietary mobile access credentials?

The Public Key Open Credential (PKOC) framework provides a non proprietary and open approach to mobile access credentials. It enables secure authentication using asymmetric cryptography, supports multiple technologies like NFC and BLE, and ensures interoperability across different systems, helping organizations avoid vendor lock-in while improving scalability and security.
